Oh, Japan! You never fail to disappoint with your downright-crazy
gadgets. Today's import from the Far East is the Tuttuki Bako, a
video game box with a hole on the side for your finger to go in.
Don't get any dirty ideas, now.
When you slip your finger inside the box, a digital representation of
it appears on the screen. You can then use your finger to interact
with games, such as playing with a tiny panda, tormenting a little
stick figure, or, uh, stroking a girls face. Not creepy at all! The
little box will sell for $30 in Japan, but I'm sure you can find it
online for import if you really want to try it out.
